A copper-catalyzed protocol for heteroarylsilylation of unactivated olefins is disclosed herein. The addition of a silyl radical to an alkene triggers a subsequent intramolecular heteroaryl migration. Heteroaryl groups such as benzothiazolyl, thiazolyl, imidazolyl, and pyridyl showcase their migratory aptitudes. A variety of heteroaryl-substituted alkyl silanes are readily generated in synthetically useful yields.
